The Rumor Mill was ablaze this week with whispers that George Clooney gave former galpal Sarah Larson the boot after she got new knockers without his OK. National Enquirer moles tell a different story. Celebrity tattles tell the tab George was not only cool with Sarah’s new chi-chis but he actually footed the $12,000 bill for the chest muscles, inspired by supermodel Gisele Bundchen, reigning Queen of the Catwalk.

“He bought her the breast implants, patterned after supermodel Gisele Bundchen’s bust,” the Enquirer spy says. ….”Last year, George paid for Sarah to have her teeth straightened. George has spent a lot of money making sure that Sarah was always well-kept and pampered…”

The tabloid claims rumors of Sarah’s infidelity were the real cause of the couple’s parting of the ways two weeks ago. George reportedly dumped Sarah after he heard she had been screwing her way around Sin City while he was working in California.

“….Once rumors got back to him that Sarah was recently hanging out with an ex-boyfriend in Vegas, he asked her to move out of his L.A home,” says a Clooney insider.

George Clooney and Sarah Larson are Splitsville. The Oscar-nominated actor has called it quits with former cocktail waitress Sarah Larson after almost one year of dating.

George, 47, and Sarah, 29, met in Las Vegas four years ago when the bubbly brunette was working at The Whiskey Bar where George was grabbing a few drinks.

“He thinks Sarah is sweet and that is why it was so hard to break up with her,” a spy reveals to In Touch Weekly.

It wasn’t until last June that the friends decided to take their relationship to the next level and officially began dating. Sarah, a one-time contestant on the defunct NBC reality series Fear Factor, sat down for a gushing interview about her relationship with the dashing Mr. Clooney in the June 2008 issue of Harper’s Bazaar.

George Clooney girlfriend, Sarah Larson, is opening up about how she met the Ocean’s Eleven star in the June 2008 issue of Harper’s Bazaar. George and Sarah first connected four years ago when Sarah was an employee at a Las Vegas resort.

“We were hanging out and dancing and being goofballs. Nothing crazy. We talked, that’s it.”

The couple began dating in June 2007:

“I got texts, and we just started talking,” Sarah says. “George is funny and sweet, and he’s good to be around. I see him as a normal person, like anyone else. He just happens to have a well-known face.”
